Hello I am a 53 year old healthy female,5'5. I recently became sexually active after 15 years. I lost 15 pounds in one month due to a viral infection, going from weighing 132 to 117. An exam showed I had a UTI that I took antibotics to clear up, but a blood test shows I have a high level of protein in my urine. I am schedule to see a kidney specialist within a few weeks. My question is did sexual intercourse cause the UTI, and high protein levels, and is it safe for me and my partner to continue to have sex.
